YAG Laser Iridotomy

Preventing Angle-Closure Glaucoma with Precision Laser Treatment

**YAG Laser Peripheral Iridotomy (PI)** is a life-changing, non-surgical procedure used primarily to treat or prevent a potentially blinding condition known as **Angle-Closure Glaucoma**. This type of glaucoma occurs when the iris (the colored part of the eye) blocks the drainage angle, causing a sudden and dangerous spike in **Intraocular Pressure (IOP)**.

The YAG laser creates a tiny, controlled opening in the outer edge of the iris. This opening acts as a "pressure vent," ensuring that fluid (aqueous humor) can circulate properly and reach the drainage channels, thus relieving pressure and preventing acute attacks.

If you have narrow angles, schedule your protective laser consultation.
Glaucoma prevention with laser

Glaucoma Prevention

The primary use is preventive care for individuals diagnosed with narrow-angles, stopping future acute attacks.

Improved fluid drainage in the eye

Improved Fluid Dynamics

Creates a permanent, open channel for fluid circulation, ensuring the iris stays away from the drainage angle.

Outpatient clinic procedure

Outpatient & Quick

The entire procedure is conducted in the clinic, typically taking less than 10 minutes per eye.

Quick relief from eye pressure

Relief from Pressure

An effective method to rapidly lower high intraocular pressure during an acute angle-closure crisis.

Frequently Asked Questions About YAG Iridotomy

**Open-angle glaucoma** develops slowly due to clogged but open drainage channels. **Narrow-angle glaucoma** (the focus of Iridotomy) happens when the physical structure of the iris blocks the drainage angle entirely, causing pressure to rise very quickly.

No. The eye is numbed with drops, and a specialized contact lens is placed on the eye for focusing the laser. You may feel a slight prick or flash of light, but the procedure is generally painless and well-tolerated.

There is virtually **no recovery time**. Patients can return to their normal activities immediately. Temporary side effects may include mild light sensitivity or slight blurring, which resolves within a day.

YAG Iridotomy effectively **cures the angle closure mechanism** and prevents acute attacks. However, you may still have chronic glaucoma that requires ongoing monitoring, and potentially medication, to manage overall eye pressure and protect the optic nerve.
